PREDET ERMINED-WEIGHT SCALE.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed March 22, 1920. Serial No. 367,659.

To all whom it may concern:

Be it known that I, ORWELL C. REEVES, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Predetermined-WeightScales, of which the following is a specification.

This invention relates to weighing scales, and particularly to theindicating mechanism thereof, and one of its principal objects is theprovision of predetermined weight indicators for enhancing theusefulness of the scale in. 'weigh ing out ingredients of -c0mpounds.

Another object is' the provision of means whereby such predeterminedweight indicators may be manipulated from without the scale.

Another object is the rovision of a device for weighing out ingre ientsof compounds which may be used by aperson to whom the mixing formula hasnot been divulged.

Other objects and advantages will be apparent from the followingdescription, in which reference is had to the accompanying drawingsillustrating a preferred embodiment of my invention and wherein similarreference numerals desi ate similar parts throughout the several views.

In the drawings Figure 1 isa front elevation of a scale dial showing myinvention applied thereto;

Fig. 2' is afragmentary central vertical section through a chart andindicating hand showing a series of predetermined weight pointers inposition; and

Fig. 3 is an enlarged fragmentary view showing the tips of theindicating hand and a predetermined weight pointer in registras tion. 1l

I have shown my invention as applied to a scale having a circular chart,but it isto be understood that the invention is also adapted foremployment with other types of scales, such, for example, as thosehaving fan-shaped charts, and that I contemplate its use whereverapplicable.

In the embodiment shown, the indicating mechanism of the scale'isinclosed within a substantially watch-casing-shaped housing having acrystal 1 through which the dial 2 and the indicator hand 3 are visible.The

indicator hand 3 is fixed upon a shaft 4 suitably connected bymeans of apinion 6 to the -indicator hand stands vertical.

weighing mechanism (not shown) of the nary weighing operations withoutdisturbing the manually movable predetermined weight pointers andwithout interference from them. I

As shown in Fig. 2, the glass front 1 of the casing is provided with anopening in which is mounteda bushing 5 to support, concentric sleeves 7and 8 and a central shaft 9 arranged in horizontal alinement with theshaft 4 carrying the indicator hand. Fixed to the inner ends of thesleeves 7 and 8 are hands or pointers 10 and 11, and a similar pointer12 is fixed to the inner end of the shaft 9.. The outer ends of thesleeves 7 and 8 are provided with knurled flanges 14 and 15 formingknobs by means of which the sleeves may be turned to swing the pointersover the dial 2. The outer end of the shaft 9 is also provided with aknurled manipulating knob 17.

The various sleeves and the bushing in the illustrative embodiment shownare snugly nested so that each will be frictionally held in the positionin which it is purposely placed. If desired, other clutching or holdingmeans may be employed. Each of the pointers 10, 11 and '12 consists of ahand having a loop-shaped outer end, to which is secured arearwardly-extending finger 18 having its tip turned inwardly, as at 19.When the indicator hand 8 egisters with the pointer, the end of the hand3 and the tip 19 of the finger are both visible through the loop (seeFig. 3). Since the end of the hand 3 and the tips 19 of all the fingersare wise distinctively marked,-and the ingredicuts in a compound may bedesignated by.

corrspondingnumbers or marks. Thus, for example, if 280 lbs. of No. lingredient are to be used in a certain compound, the No.

10 pointer is set at 280. lbs. on the chart, and if 320 lbs. of No. 2ingredient are tobe used, No. 11 pointer is set at 600 lbs., the sum of280 and 320 lbs., and so on until a pointer is set for each ingredient.All that the Operator has then to do is to put in No. l ingredient untilthe indicator hand points to No. 10 predetermined weight pointer, addNo. 2 ingredient until the indicator hand points to No. 11 pointer, andso on. He need not keep in mind or even know the numbers of pounds ofthe various ingredients, and need make no mental calculation whatever.

When the scale is to be used for secret compounding the dial may be leftblank. The foreman or other authorized person may then set such of thepointers 10, 11 and 12 as are to be used by means of master Weights. Thecompounding may thus be effected without divulging the formula even tothe operator of the scale.

While it will be apparent that theillustrated embodiment of my inventionherein disclosed is well calculated to adequately fulfil the objectsprimarily stated, it is to be understood that the invention issusceptible to variation, modification and change within the spirit andscope of th subjoined claims.

Having described my invention, I claim:

1. In a device of the class described, in combination weighingmechanism, an indicator shaft connected thereto, an indicator hand fixedto said shaftand-- capable of a complete rotation and'a} plurality ofmanually-operable hands rotatably mounted on an axis substantiallycoincident with that v of said indicator shaft.

manually-operable hands rotatably mounted 2. In a device of the classdescribed, in.

combination weighing mechanism, an indicator shaft connected. thereto,an indicator hand fixed to'said shaft, and a plurality of on an axissubstantially coincident with that of said indicator shaft,said'indicator hand and said manually-operable hands having pointingtips lying in substantially the same lane.

p 3. In a device ofv the class described, in

combination, a dial, an indicator shaft projecting through saiddial, anindicator hand fixed'to said shaft, a transparent plate overlying saiddial, and a plurality of manually-operable hands mounted on said plate.

4. In a device of the class described, in combination, a dial, anindicator shaft projecting through said dial, an indicator hand fixed tosaid shaft, a transparent plate overlying said dial, and a plurality ofmanuallyoperable hands mounted on said plate and having operating knobsprojecting outwardly therefrom, the pointing tips of all of said handslying in the same plane.

5. In a device of the class described, in combination, a dial, anindicator hand cooperating therewith, a plurality of manuall'y-operablehands rotatably mounted on an axis substantially coincident with theaxis of rotation' of said indicator hand, each of said manually-operablehands having a loop-shaped end and a pointing tip behind saidloop-shaped end whereby the said pointing tip and the tip of saidindicator hand are visible through said loop when said tips are inradial alinement.

6. In a device of the class described, in combination, weighingmechanism, a dial, an indicator hand connected to said Weighingmechanism and cooperating with said dial, a plurality ofmanually-operable hands rotatably mounted on an axis substantiallycoincident with the axis of rotation of said indicator hand, each ofsaid manuallyoperable hands having a loop-shaped end, and a pointed tipbehind said loop-shaped end, whereby said pointed tip and the ti of saidindicator hand are visible throng said loop when said tips are in radialalinement.
